Facelifted from `2020`, the `RS5 Sportback F5` becomes the most mature form of this very fast family car. The technical core changes little, but the presentation, infotainment and electronic integration move forward. Against a BMW 5 Series or a heavily powered Mercedes C-Class, it remains a distinctive proposition: five doors, a real boot and proper performance-car pace.
The package still revolves around the `2.9 TFSI`, the `ZF 8HP` and `quattro`, with the same demands for thermal control, cooling health, engine follow-up and clean gearbox operation. On this later phase, you also need to read software, `ADAS`, sensors, the `12 V` battery, the tailgate and the comfort electronics. A good facelift car has to feel right both mechanically and digitally, with no stray warnings and no body details that suggest careless use.
